Abstract
A learning system is disclosed that comprises ordered pairs of interlocking cooperatively aligned hexagonal bosses and recesses having one or more peripherally disposed lobes as control structures to influence a user to connect or assemble articles or objects in a predetermined sequence or positional relationship.
Claims
exact text as granted — not AI-modifiedI claim:
1. A learning system comprising at least two objects having cooperatively aligned, releasably interlocking hexagonal control structures for joining the objects in a predetermined sequential and positional relationship, the hexagonal control structures comprising ordered pairs of hexagonal bosses and recesses having one or more peripherally disposed protuberant lobes.
2. A learning system comprising at least two objects having cooperatively aligned, releasably interlocking hexagonal control structures for joining the objects in a predetermined sequential and positional relationship, the hexagonal control structures comprising ordered triplets of hexagonal bosses and recesses having one or more peripherally disposed protuberant lobes.
3. A learning system comprising at least two objects having cooperatively aligned, releasably interlocking hexagonal control structures for joining the objects in a predetermined sequential and positional relationship, the learning system further comprising at least one neutral object having at least one surface with a plurality of male hexagonal neutral structures projecting outwardly from the surface, and at least one other surface having a plurality of female modified neutral hexagonal constrol structures recessed into said other surface, each female modified neutral hexagonal control structure having six sides and each side incorporating a recessed lobe.Join the waitlist — get patent alerts
